A rare "Sport" model was produced in 1985 to homologate for the sub 1,300 cc class of Group A for the British Rally Championship. These sport models were white and came with unique vinyl decals, a 13SB engine with twin Weber 40 DCOE carburettors, an optional bespoke camshaft, a replacement rear silencer, and few luxuries. This gave 93 hp and a top speed of 112 mph (180 km/h) with a 0–60 mph time of 8.9 seconds. These are by far the rarest models (500 produced) and thus acquire a high market price if one does become available.
This Chevette went throu several redesigns — first front an rear panels seemilar tae the Opel version, then a leuk seemilar tae the Breetish Vauxhall Chevette, an finally a design reminiscent o the updatit USA Chevrolet Chevette version. It wis available in several different bodies: hatchback (1979–87), estate (cawed Chevrolet Marajó, 1980–89), pickup (Chevy 500, 1984–95) an saloon (1973–93). The Chevette sauld ower 1.6 million units in Brazil, bein replaced bi the Chevrolet Corsa.
Although GM's passenger vehicle line-up in South Africa consisted of Opel-based models by the late 1970s, these were sold under the Chevrolet brand name, with only the Kadett being marketed as an Opel when it was released in 1980. In 1982, the Chevrolet brand name was dropped, with the Ascona, Rekord, Commodore, and Senator being rebadged as Opels.
The basic trim level was called just the Corsa, which was followed by the Corsa Luxus, Corsa Berlina and the sporty Corsa SR. The SR receives a spoiler which surrounds the rear window, alloy wheels, checkered sport seats, and a somewhat more powerful 70 PS (51 kW) engine. Six years later, the Corsa received a facelift, which included a new front fascia and some other minor changes. The models were called LS, GL, GLS and GT.
The GSi's engine mapping had been carried out by Opel tuning specialists Irmscher. A model with the 82 PS (60 kW) 1.4 L multi point fuel injected engine, which was otherwise mechanically identical to the GSi, also became available as the Nova SRi in the United Kingdom. In January 1988, a turbocharged version of the Isuzu diesel engine was introduced, with power increased to 67 PS (49 kW).
